Answer:
a) Let her comic books be x
b) as she sold half it will be
+ 8 = 13 ( as she sold half and then she bought 8 more that means plus and then now she have 13 that means = 13)
c ) to solve to find the books she have we need to
+ 8 = 13
Transpose
= 13 - 8
= 5
x = 5 × 2
x = 10
the comic books were 10
we can even cross- check to see if the value is right instead of x put 10
+ 8 = 13
5 +8 = 13
13 = 13
Cross-checked
Hello and Good Morning/Afternoon:
<u>Let's take this problem step-by-step</u>:
<u>What does the information want:</u>
<u>Let's gather some information</u>:
- ΔA'BC' and ΔABC are similar triangles
⇒ Angle B is shared by both triangles
⇒ Angle A' and A are the same, as they are both on parallel
lines, A'C' and AC, and both angles are formed with the
same line AB
⇒ by the <em>Angle-Angle Theorem*</em>, they are similar triangles
<u>If they are similar triangles</u>:
⇒ their side lengths are proportional to each other
⇒ let's set up a proportion

⇒ let's set up a proportion

<u>Answer:</u>
- <u>x= 17.143</u>
- <u>y = 26.25</u>
Hope that helps!

Length of the cylinder = 84.5 cm
Diameter of the cylinder = 2.40 cm
The circumference is
π(2.40 cm) = 2.4π cm.
The area is
A = (2.4π cm)*(84.5 cm) = 637.1 cm²
Answer: a. 637 cm²
Answer:
12m + 12 is one equivalent expression
Step-by-step explanation:
This can be found by distributing the numbers as shown below:
6(m + 2 + m)
6m + 12 + 6m
12m + 12
solution:
we know that ,
u.v = ΙuΙ ΙvΙcosθ
here,
θ =60° (since the given triangle is equilateral triangle)
u.v = ΙuΙ ΙvΙcos60°
= 1 x 1 x 1/2
u.v = 1/2
now, u.w = ΙuΙ ΙwΙcosθ
= ΙuΙ x cos(60x2)
u.w = -1/2
